Using solid-state spin defects for Nano & Microscale NMR spectroscopy
Our group uses nitrogen-vacancy (NV) centers in diamonds as atomic-scale sensors. With these quantum sensors, nuclear magnetic resonance (NMR) signals from unprecedented lengths scale down to a few cubic nanometer sample volumes or even single molecules can be detected. We aim to establish NV-diamond NMR as a novel tool in chemistry and life sciences by an interdisciplinary approach at the interface of chemistry, physics, and biology with a focus on the following topics:
•Surface NV-NMR spectroscopy with applications in catalysis and material science
•NV-NMR microscopy for probing metabolism on the single-cell level
•NV-NMR on-a-chip for microscale analysis high-throughput screening
•Development of novel quantum materials with spin defects

Abstract: Microscopy enables detailed visualization and understanding of minute structures or processes. While cameras have significantly advanced optical, infrared, and electron microscopy, imaging nuclear…
Nature Communications
Abstract: Battery development pivots around understanding the complex processes governing battery operation and degradation. Most degradation pathways link structural and chemical inhomogeneities with strongly…
ACS Central Science
Abstract: How life developed in its earliest stages is a central but notoriously difficult question in science. The earliest lifeforms likely used a reduced set of codon sequences that were progressively…
Applied Physics Express
Abstract: Optimal conditions for creating shallow ensemble nitrogen-vacancy (NV) centers in a 12C-enriched diamond were investigated. NV spin properties, created by implantation of 15N+ ions with 2−5 keV…
